USB wired internet with LG V10 is unstable

[Kristian]

I experience frequent network connection drop-offs.
My laptop is an Asus ux32vd with an Intel Centrino Advanced-N 6235.

I've got problems maintaining internet connection through USB with my LG V10 phone.
I cannot establish an internet connection through bluetooth with my phone.
Using a 'wired' connection with USB internet sharing does only work for a few minutes, then the connection drops off.

I've updated Ubuntu to the current version and tried with a clean install a few weeks ago.
I've also tried installing alternate drivers for the Intel network adapter.

Restarting Network Manager services does not solve the situation.
